Welcome to blogger help forum!
Firstly let me clear your one thing that there is no blogger account.Blogger is an CMS or a free hosting platform in easy words. This is owned by google and you have to use your current gmail account to sign in.
And also its a blog not a website
Ok so lets get in!
first go to
www.blogger.com then signin with your google account then there will be two options one to create a blogger profile and one to use existing google profile,the choice is yours!
after that There you will find a new blog button and then click over there a dialog box will appear add your blog title and url (yourblog.blogspot.com) you can add custom domain later.
then select the theme which you want (there are themes like picture window,default ,simple etc) and now you are sone with creating a blogger blog.
Now time to post!
navigate to the blogger blog and click on the title and click on the orange button which says NEW POST and then write and publish it.
Then you are done! you can also install custom blogger templates
